    Study Notes

    Reactivity Series of Metals

    • Metals are ranked in order of reactivity based on their reactions with water, acids, and oxygen.
    • More reactive metals react more vigorously with these substances.
    • The reactivity series helps predict which metals will displace others from their compounds.
    • The series includes non-metals like hydrogen and carbon, as they are used to extract metals from their oxides.

    Reactivity Series - Reactions with Water

    • Potassium and sodium react violently with cold water, producing hydrogen gas.
    • Calcium reacts less vigorously, also with cold water.
    • Magnesium reacts slowly with steam.
    • Aluminium also reacts slowly with steam.
    • Zinc, iron, and metals below them in the series do not react with cold water but react with steam to form metal oxides and hydrogen gas.

    Reactivity Series -Reactions with Acids

    • Metals above hydrogen in the reactivity series react with dilute acids to produce hydrogen gas.
    • Metals below hydrogen do not react with dilute acids.
    • The more reactive the metal, the more vigorous the reaction with acids.

    Reactivity Series - Reactions with Oxygen

    • More reactive metals such as the alkali metals react readily with oxygen.
    • Less reactive metals such as copper and iron also react with oxygen, but more slowly.

    How to Remember Reactivity Order (Mnemonic)

    • A simple mnemonic aid is provided to memorize the order: "Please send cats, monkeys, and cute zebras into hot countries signed Gordon"

    Displacement Reactions

    • A more reactive metal can displace a less reactive metal from its aqueous solution of a metal salt.
    • The reactivity of the metal is the key factor, not the amount of metal used.
    • The displaced metal will be deposited as a solid.

    Rusting of Iron

    • Rust is hydrated iron(III) oxide, formed by the reaction of iron with oxygen and water.
    • Rusting requires both oxygen and water.
    • Preventing rust can be achieved by using barrier methods such as paint, grease or plastic.

    Galvanizing & Sacrificial Protection

    • Galvanizing involves coating iron with zinc to protect it from rust since zinc is more reactive than iron.
    • Sacrificial protection uses a more reactive metal (e.g., zinc) to protect a less reactive metal (e.g., iron) from corrosion. The more reactive metal preferentially corrodes.
